Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 843-872, May 2026.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

The fundamental group of the complement of a generic fiber‐type curve

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract In this paper, we describe and characterize the fundamental group of the complement of generic fiber‐type curves, that is, unions of (the closure of) finitely many generic fibers of a component‐free pencil F=[f:g]:CP2⤍CP1$F=[f:g]:\mathbb {C}\mathbb {P}^2\dashrightarrow \mathbb {C}\mathbb {P}^1$.

Phase‐Field Fracture Simulation of Pressurized Concrete Microstructure

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT Pressurized cracks in concrete have a significant impact on the safety and durability of concrete structures. The peak strength of concrete is reduced in the presence of pressurized cracks. However, conducting pressure‐coupled strength evaluation experiments requires extensive effort, and simulation tools can complement the time‐consuming and ...
